CAR=WHEEL- SPECIFICATION forming part of Letters Patent No. 356,885, dated February l, 1867.

Application filed August 12, IESS. Serial No. Q09, me.

T o @ZZ whom t may concern.-

Be it known that I, Encan Prieur-mir, of Syracuse, in the county oi Onondaga, in the State of New York, have invented new and useful Improvements in Car-Vifheels, of which the following, taken in connection with the accompanying drawings, is a full', clear, and exact description.

rlhis invention consists in a novel construction of a car-wheel composed of concentric sections arranged one over the periphery of i-heotherand a soft-metal bush inserted in the joint of said sections to relieve the wheel from the crystnllizing influences and undue strain incident to the jars the wheel is subjected to and render it noiseless, all as hereinafter more fully described, and summed up in the claims.

The invention is fully illustrated in the annexed drawings, wherein- Figure l is a side elevation of my improved car-wheel. Fig. 2 is a transverse section of the same. Fig. 3 is a side View of the hub,

bare of the other parts of the wheel. Fig. 4 is a detached side View of the collar by which the web or body of the wheel is retained on the hub. Fig. 5 is a detached side View of the key by which the tire-retaining ring is secured in its seat on thetire. Fig. 6 isa detached side view of the clamp by which the aforesaid key is retained in position.

wheel, and Fig. S is a detached transverse sectional View of the tire.

Similar letters of reference indicate corresponding paris.

A represents a ear-axle, and H the hub of the wheel, which hub is rigidly secured to the axle in any suitable and well-known manner. flfhe inner end of the hub is formed with a circumferential ilange, F, and with a circumferential rib, F', on the side of said flange facing toward the outer end oi" the hub, and from this rib part way toward the hub project lugs Z Z.

a denotes a bushing or sleeve of either Babbitt metal or lead, or copper, or other suitable soft metal, extending froxn the flange F part way the length of the hub, and at the outer end of said bushing is a circumferential groove, c, in the hub, leaving a collar, d, at the outside of the groove.

Fig. is a detailyiew of the inner face of the body @y web of the (No model.)

0n the soft-metal bushing a is seated and snugly fitted the web or body B of the wheel, which may loe composed of either cast or wrought iron or steel, and may be either holy lugs Z Z, extending only part way toward the hub. allow the body B to yield radially in its position and yet retain its bearing on the softinetal bush.

On the outer side of the bodyB is a removable collar, C, which is divided diametrica-lly into two sections, so as to allow the said collar to be seated into the groovecof the hub. The eye of the collar C is formed with an inwardprojecting {lang-e, e, which enters the groove c i aforesaid, and the collar which is formed on the end of the hub, serves to retain the collar C on the hub. By means of bolts ff, passing through the collar C, body B, and ila-nge F, the said collar is clamped against the side of the body B.

T represents the tire, preferably composed of steel. This tire l secure to the body B by forming the said tire with a circumferential rib, z, at one edge of the inner peripheral face thereof, which rib abuts against one side of the body B, as shown in Fig. 2 of the drawings.

At the opposite side of said body and adjacent thereto l provide the inner peripheral face of the tire with a circumferential groove, Zi, leaving a circumferential shoulder, i, at the outer side of the said groove, and into this groove I insert the retaining-ring R, which is composed of two or more segmental sections, so as to permit of its introduction into the groove. l prefer, however, -to forni it of two nearly seniicircular sections and a key, m, entering between the ends of the aforesaid sec` tions, as represented by dotted lines in Fig. l of the drawings. The key is provided with a lug, m', on vits outer side, and across the exterior ICO of said key and. adjacent end portions of the ring-sections I place a clamp or plate, n,whieh .is provided with an. eye for the reception of the lug m, and is secured in position by bolts 5 o o, passing` through said clamp and through the ring-sections and body B, as illustrated in Fig. 2 of the drawings. The ring` R is further secu red in its position by additional bolts, o o, passing through the ring and body B.

It will be observed that by the employment of the groove 7L and shoulder t' on the inner peripheral face of the tire, with the retainingring R seated in said groove at one side ofthe body B, and the rib tl'ormed on the tire at the I5 opposite side of said body, the tire is conned laterally between shoulders formed integral with the tire, and therefore it is niost securely retained in position.

I do not here claim, broadly, a car-wheel zo composed ol a central body, a tire formed on its inner peripheral face, with shoulders or flanges at opposite sides of the aforesaid body,

and a retaining-ring inserted between one of said shoulders and adjacent sides of the body.

25 Such a combination of parts is shown `in other applications for Letters Patent filed by me August 2 and August 4, 1886, Serial Nos. 209,759 and 209,942.

lVhat I claim as new, and desire to secure by Letters Patent, is-

1. A car-wheel composed of a hub, a softniefal bush encircling,` the hub, a web or annular body seated upon the said bush, and a tread on said body, substantially as set forth and shown. Y

2. The combination of the hub H, formed with the flange F, circumferential rib F, and lugs Z Z, projecting from said rib toward the hub, and the body B, formed with the annular rib r, projecting` from the side thereof, and 4o notches ln in said rib, and the bush b, inserted between the hub and eye of the body, substantially as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence 45 oi' two attesting witnesses, at Syracuse, in the county of Onondaga, inthe State of New York, this 31st day of July, 1886.
